Disable metadata "folders"

[Former user]

I would like to be able to add just the metadata folders I need (or no folder at all if I think so).

For example, I might not want a Movies ou Series folder, or no Artist and Director, etc. I think it must be easy to implement (maybe just another tab in the Console to tick the folder you want to show) and useful to a lot of people that want a cleaner browsing experience.
